Payback with Mel Gibson as well as the original, Point Blank with Lee Marvin are both good movies for revolvers (particularly if you like 4" N-Frame Smiths). Death Hunt with Charles Bronson and Lee Marvin also has some good revolvers in it but it's best for those who like vintage rifles (Bronson uses a Savage 99 while Marvin uses a Krag carbine IIRC).
